Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed, and patented an event detection system and device that detects events of interest such as damage events associated with impacts, interactions between structures, or structural integrity events. This patent also incorporates an acoustic detection system including microphones to detect sound waves to determine the direction of the source of the projectile. The processor in this system uses the measurement of the sensors and the sound waves to determine the event origination axis. This invention also has an imaging system to detect fire flash with a camera and correlate with the processor and data from the impact sensing device. A look-up table of signature data associated with the the impact sensing devices, acoustic detection system, and the imaging system. This invention also includes a method of detecting a damage even associated with a structure of interest that include damage sensing, sound waves, and flash events to determine damage event origination axis.
